Ontario Tree Seed Transfer Policy Zones And Climate Similarity

Ontario Tree Seed Transfer Policy data provides rules for collecting and deploying tree seeds to ensure forest regeneration success. It includes three tables detailing acceptable seed transfers between historical seed zones and current ecodistricts based on climate similarity analysis. The Government of Ontario maintains this policy data, last updated in March 2026.

Use Cases

• Identify acceptable seed sources for a target ecodistrict using Table 2's 'Acceptable seed transfer from the 2010 Seed Zones of Ontario to ecodistricts'.
• Plan seed deployment between ecodistricts by querying Table 3's 'Acceptable seed transfer among ecodistricts' for climate similarity scores of 0.9 or greater.
• Transition from old to new seed zones using Table 1's 'Acceptable seed transfer from the 2010 Seed Zones of Ontario to current seed zones'.
• Visualize seed collection and deployment options using the interactive maps for specific counties or management units.

Strengths

• Data is provided in multiple formats including CSV, XLS, and shapefiles for flexible use.
• Includes an interactive map for visual analysis of seed transfer decisions based on climate similarity.

Limitations

• The specific row counts and sample sizes for the three core tables are not provided.
• The dataset is highly specialized for Ontario, Canada, limiting its geographic applicability.
